After bringing your attention to Shedworking, a blog for living and working in small places, I had to post this link to an article I stumbled upon over at LifeHacker. One of their readers, Brian DeHamer, solved his lack of office space in his house by constructing a toolshed behind his garage and converting it to a state of the art office! The office is fully insulated and complete with multiple monitors, carpet, track lighting, and plenty of storage space. Check it out.
This is very inspiring for my own shed living project. My plan was to have one of three shed units be a combined sleeping, office space. One thing I really like about the design above is the ability to isolate yourself from the rest of the living space. In my current living arrangements, my office and sleeping space is combined, which can make it difficult to work while the wife is trying to sleep. It might be time to rethink the office/sleeping unit.
